EXTENSIBLE TABLE.

Application filed February 19, 1916.

To all whom it may concern Be it known that I, GIUSEPPE BELLUSCI, asubject of the King of Italy, residing at New Haven, in the county ofNew Haven and State of Connecticut, have invented certain new and usefulImprovements'in Extensible Tables, of which the following is aspecification.

One of the objects of this invention is to provide an extensible tablevwhich shall be 7 extremely simple in construction, economical in cost,and thoroughly efficient in operation and durable in use.

A further object is to provide a table of this character which may beextended or contracted with a minimum of manual effort and with amaximum of celerity.

A further object is to provide a table of this character which shall notbe bulky, cumbersome, or heavy, but which, on the contrary, shall belight in weight and exceedingly compact. 1

A further object is to provide an extensible table, the mechanism ofwhich is designed so as to obviate likelihood of itsgetting out oforder.

A further object is, to provide an extensible table, the mechanism ofwhich is so simple as readily to be understood by persons of nomechanical ability.

Other objects of specific improvement, g0- ing to make up the ultimateperfection of the entire device, will appear as the specificationproceeds and the nature of the invention more fully appears.

The invention is graphically portrayed in the accompanying drawings,which disclose illustratory form of embodiment of the invention capableof carrying out the underlying principles thereof.

Like reference-characters denote corresponding parts throughout theseveral views.

A brief description of the different figures of the drawings may begiven as follows:

Figure 1 is abottom plan view of the table in extended position, thebottom cover-plate being shown broken away to more clearly show theinterior mechanism, andthe tablelegs being shown in section; Fig. 2 is alongitudinal section, on the line 2-2, Fig. 1, looking in the directionof the arrows; Fig. 3 is a bottom plan view of the table in itscontracted position, they table-legs being shown in section, and thebottom cover-plate being removed for purpose of clearness 'oflllllSlDI-fiiiifill of other parts; Fig-4 is a trans-3 Specification ofLetters Patent.

Referring, now, in detail to the drawings: The table-frame includes two,longitudinally-extending, vertically-disposed sidebars 1, 1, at the endsof which are the four table legs 2. Each of the side bars is provided,on its rear face, with two, longitudinally-extending grooves 1, 1 in thesame horizontal plane, and each extending from a table leg 2 to a pointnear the longitudinal center of the side-bar 1. The purthereof.Guide-strips 6, 6 are carried by the tops of said members 3, 3, at'thefree edge thereof. The purpose and function'of the bed and theguide-strips will appear hereinafter.

Slidable on top of the side-bars 1, 1 is the table top, comprising two,main leaves 7, 7, each of which carries, on its under surface,

two angle-portions 8, 8 engaging two of the grooves 1 in the inner faceof the side-bars l, 1, whereby the main leaves 7, 7 are guided in theirsliding movement, and whereby they are held against accidental removalfrom' said side-bars.

"Each table-leaf 7 carries,- on its under surface, two blocks 10, 10,which are connected by two strips 11, 11. Reciprocablelongitudinally ofeach pair of strips 11, 11 is a slide 12 disposed between said stripsand the under surface of the main table-leaves 7, 7, and provided withangled ends 12 12 in juxtapositionto the sides of the strips 11, 11.Each slide 12 carries a boss 13 projecting between the strips 11, 11,and in these two bosses are secured the ends of a suspension-rod 14;Pivotally and slidably supported on thisrod 14 are two or more swinging,supplemental table-leaves, each "mental leaves.

Also, hooks 7, pivoted atone end thereof, as at 7 to the under surface of the main table-leaves7, 7, near the outer edges thereof, are adapted to engage pins 7 hcarried by the supplemental end table-leaves 1819, when the said leavesare in operative POSllZlOIl, as shown 1nF1gs.. 1

and 2, to, hold them against separation from the main table-leaves 7, 7..Additional hooks.

A cover-plate 50 may be secured to the bottom of the members 3, 3 and 1,4:, if desired, to hide the interior mechanism of the table.

The operation of the deviceis as follows:

In theposition of the table wherein all the supplemental:leaves are11111188, as shown 1n 1 and 2, the ends of the supplemental leaves 1819,,1,819 are supported, against side-bars 2122, 21.22. Thetwo'intermediatesupplemental leaves l5-16,151-6 are supported uponvthetops of the-side-barsl,

1, and, in the operative position thereof, are

locked against collapse by theirpins -3O1engaging correspondingrecesses'in the edge of the mainileaves 7, 7 and'by the catches 7*, 7carried by thermainleaves'7, 7. To

collapse'the supplemental leaves, so as to .brmg'the tableto:the;position showniiniFig.

3, the table top: pulled, "atieach: end, so as to separate :01rdisengage" the pins 30 in the the corresponding openings inrthe; sides:of ad acentg-table leaves, and the'catoh'es 7 7 arethenedisengaged.Each section 16 of the two "center supplemental f leaves is' then swungupward, 1n the directlon indicated the arrow at the left in Fig.'6,"ontothe section 1.5, then, the two sections 15,16 are swung-in" the reversedirection, or in'the direction indicated by: the arrow at the right inFig. 6, so that the two superposed "sec- .ti0nsr15,16wi1l occupya'positionpas shown ,sidesfofatheileaves from engagement with i indotted lines in Fig. 6, beneath the tabletop. In this position, the twosections willoccupy an inclined position, with their lower endssupported upon the upper surface of the cover-plate 50, or, if thelatter is not used, downward movement of the sections 15, 16 will belimited by the bar or brace 5. The operator then pushes against the sidebars 24, 24 of the extensible traveling carriages which carry the endsupplemental leaves 1819, 1819, so as to move said carriages toward eachother and bring the two main leaves 7, 7 toward each other, to partlyclose the opening previously occupied by the supplemental leaves 1516,1516 before they were swung down from the fullline position to thedotted line position thereof shown in Fig. 6. As the slidingcarriagesare moved, as described, the end supplemental leaves 1819, 18-19 pushagainst and move the main leaves 7, 7 to ward each other, to partlyclose the opening previously occupied by the supplemental leaves, asdescribed. In such position oi the carriages, the end supplementalleaves may be pushed inward, so as to remove them from support by theend bars 24, 2 1. The catches 7 and the hooks 7 are then disengaged, thesections 18 of said supplemental end leaves are then swung upward. inthe direction indicated bythe arrow at the left in Fig. on top of eachother. As the sections 18 are swung upward, as described, on theirpivots 26, the inner or hinged end of said sections move downward, asshown in dotted lines in Fig. 5, which pulls the sections 19 in thedirection indicated by the two arrows at the right in Fig. 5, whereby,in the collapsed position of said end supplemental so that the twosections lie one leaves, they occupy a position as shown in full linesin Fig. 5, downward movement being limited by the stops 28. The end bars241, 24 are then pushed so as to move the traveling carriages towardeach other a little more, thereby entirely closing the openingpreviously occupied by the center supplemental leaves .1,5, 16, 15, 16.The table is now in the contracted position shown in Fig. 3, and thehooks 7 carried by one of the main table-leaves 7 are engaged with thepins 7' carried by the other main leaf, so as to lock the table-leavesagainst accidental separation.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

In an extension table, two slidable main table leaves, horizontallyslidable, supplemental table-leaves foldable and movable from a positionbetween and in the same horizontal plane as the main leaves to aposition beneath each of the same, two sliding carriages disposedbeneath said main leaves, two supplemental, foldable end leavessupportable, in unfolded position, upon the tops of said carriages, tworods carried, at one end thereof, by said carriages, upon which saidsupplemental leaves are pivotally and horizontally-slidably mounted, andbrackets carried by said carriages and secured, at their free ends, tothe other ends of said rods.

In testimony whereof, I aflix my signature in the presence of twowitnesses.
